Key legal question
Whether the subsidiary constitutional complaint was admissible to challenge the denial of cantonal tax remission
Extracted holding
No enforceable right to remission existed under Solothurn law, so review for arbitrariness was unavailable; only procedural rights could still be invoked.
Extracted reasoning
Section 182 StG/SO and the implementing ordinance leave remission to administrative discretion and do not create a justiciable entitlement.
